This will not help. Try:
#!perl
my %hash;
%hash = (
a => 1,
b => 2,
c => $hash{a},
d => $hash{b},
);
use Data::Dumper;
print Dumper(\%hash);
You have to split the hash creation:
%hash = (
a => 1,
b => 2,
);
$hash{c} = $hash{a};
$hash{d} = $hash{b};
use Data::Dumper;
print Dumper(\%hash);

P.S.: Sorry if I got lost in the code and misunderstood your
suggestion.
